A Message from Genesis

Congratulations! And Thank You!

You are now the owner of one of the finest loudspeaker systems in

the world! The Genesis 2.2 is the result of technologies developed

and refined over the past 40 years in constant production.

The G2.2 loudspeaker system was created for the music lover who

knows (almost) no compromise. It is designed to reproduce music

(and film) at live listening levels with virtually no restrictions on

dynamic range, frequency response, or imaging capabilities. This is

“

absolute fidelity™”, the ability to reproduce the musical event

faithfully, as was intended by the performer or filmmaker.

However, the G2.2 is not meant to reproduce music at ear-splitting

levels. If you are looking for just LOUD, this is the wrong

loudspeaker. A Ferrari and a Caterpillar may have the same price

and horsepower, but they are very different vehicles and you

wouldn’t use your Ferrari to move a load of gravel.

Please read this Owners Manual and Set-up Guide to get the

maximum enjoyment out of your purchase. Also, if you have

access to the internet, please check back at our website often. The

address is www.genesisloudspeakers.com

. We will put the latest

updates, tips and tricks, and support for our owners on our website

and in our newsletter.

Please write the purchase details of your Genesis 2.2 System

here for future reference. Remember, send in your registration

card to extend the limited warranty on your loudspeakers.

Set-up Guide

Now that you have your new Genesis 2 loudspeaker system, we

realize that you can’t wait to hook it up and start the music!

However, this is a big, complex system and we want you to set it

up correctly and more importantly, safely. So, please read this set

up guide (even if your dealer is setting it up for you!) before you

proceed.

Planning the Placement

Before you even have the loudspeakers delivered, it would be a

good idea to make a plan of where you will place them. You will

not need a huge room, but at a minimum the room should be about

16 feet (5m) wide where the speakers will be placed. You should

have a minimum of at least 6 feet (2m) of space behind the

speakers. The listening position should be a minimum of 10 feet

(3m) from the front of the midrange ribbon to allow for proper

integration of the drivers.

In a typical placement, the midrange/tweeter wings will be placed so

that the two columns of tweeters are on the inside, and between six

feet to eight feet (2m to 2.6m) apart. The woofer towers are placed

behind and outside the wings with the column of woofers about 4 feet

absolute fidelity

from the midrange ribbons. In order to allow for sufficient space from

the sidewalls, this dictates that the optimum room is at least 19 feet

(6m) wide.

Placing the woofer towers asymmetrical but equidistant from the

midrange/tweeter wings will result in better integration of the bass

frequencies to the room. Keep the side of the woofer towers no

less than 16 inches from the sidewall.

The suggestions here are typical in a minimum space. With a larger

room, it is possible (and optimal) to have a layout as shown below

with the midrange, tweeters and woofers equidistant from the

listening position. Still, the woofer towers should be placed

asymmetric in the room with the distances of the woofers from the

absolute fidelity

nearest wall being different.

As the room will greatly influence the sound of your system, fine-

tuning adjustments in placement will be necessary. Every room will

be different, with doorways, furniture, closets, wall construction and

covering, etc. all making a significant impact on positioning.

Unpacking

The Genesis 2.2 system will arrive in a number of pieces. There

are four large wooden shipping crates, two containing the woofer

towers, two holding midrange/tweeter panels (or “wings”). There

will also be a pallet of cardboard boxes holding the acoustic

suspension system, the various modules of the servo-controlled

bass amplifier, and a box containing the various cables. (There

could also be up to three more boxes if you have the optional

Maximum Dynamic Headroom Reservoir and power supply

upgrades to the servo-controlled bass amplifier.)

To remove the contents of all the crates, you will need help. The

G2.2 loudspeaker system with crates weigh a total of 1,400 lbs.

Each woofer tower weighs over 220 lbs, and each tweeter tower

weighs over 150 lbs and they have to be lifted out of the shipping

crates. We are not liable for damage (to either the speakers or

your backs!) during unpacking and setting up.

We suggest the use of a forklift to move these

crates around, and at least four strong people to

un-box and position the loudspeakers. In order to

remove the loudspeakers from the crates, the front

and top of the crates can be removed. This is

secured with screws – remove all exposed screws

except the ones marked with blue paint – and the

top and front can be lifted away.

With the top and front of the crate removed, each

wing and tower of the loudspeaker can be carefully

lifted and slid out of the crate. Before you put the

speaker up on its feet, it will be necessary to install

the acoustic suspension (next page).

After unpacking, we strongly suggest that the crates be dismantled,

flattened and safely stored away in a cool, dry place. They will be

needed should you relocate or move. It will be expensive to custom

absolute fidelity

build crates strong enough to transport these loudspeakers without

damage.

Assembling the Acoustic Suspension

A unique feature of the Genesis 2.2

loudspeaker system is the integration of an

acoustic suspension system for the

loudspeaker columns. This is an essential

feature of the cabinet structure – resulting in

lower coloration, better definition and rock-

solid imaging.

The suspension system comprises of a

suspension frame made of 1-inch of solid

cast acrylic, a set of Neoprene decoupling

shock absorbers, and a set of steel spikes.

Should you be placing the speakers on a hardwood floor or a floor

that would scratch easily, do not use “spike cups”. These defeat the

purpose of having a spike in the first place! Use a copper penny –

the weight of the speaker on the spike will create a depression in

the penny, and this point is what will efficiently transfer vibration to

the floorboards.

A couple of points to note during the assembly of the acoustic

suspension system:

1) The triangular “hole” in the suspension frame points to the

front of the speaker (towards the listener).

2) Do not over tighten the shock absorbers that are pre-

installed on the cabinet – finger tight is sufficient. A hex-key

(or allen wrench) is supplied to tighten the bolts holding the

suspension frame to the shock absorbers. Again, do not

over tighten these bolts.

3) The point of the spike should protrude through the

suspension frame only far enough to couple to the floor. If on

a concrete or marble floor, for example, 5mm or 1/5” is more

than sufficient. If you have your speakers on a 1/2" deep pile

carpet, then you will need to have the spike protrude about

3/4" so that the suspension frame clears the carpet.

4) If you need to move the loudspeaker after you have installed

the spikes, do not “walk” the speaker cabinet on the spikes –

retract the spikes first, shift the speakers, and then lower the

Acoustic Suspension under the

midrange/tweeter wings

absolute fidelity

spikes again. This will avoid causing damage to the acoustic

suspension and to your floor.

5) While the acoustic suspension is designed for you to be able

to use the system on any surface, if you have very light and

resonant bare floorboards, you may need to place a heavy

slab of marble, slate, or granite under the loudspeaker to

avoid exciting the floor.

The Servo-Controlled Bass Amplifier

The included remote-controlled

modular Servo-Controlled Bass

Amplifier powers the woofer

towers of the G2. There are

three modules, an acoustic

suspension (or amplifier stand)

plus a power supply unit and

numerous supplied cables in

the standard configuration.

The parts of the amplifier are:

1) The electronic crossover and Control Module with left

and right balanced inputs and two control outputs.

2) A pair of Control Interface Cables (CIC): these have

7-pin Neutrik™ connectors at each end.

3) A pair of Servo-Bass Interconnects (SBI) with XLR

connectors at one end and a pair of banana plugs (or

optionally spades) at the other end.

4) Two Servo-feedback Amplifier Modules with one

control input, and two Neutrik 50-amp Speakon™

outputs.

5) One Acoustic Suspension system.

6) Two pairs of Servo-Bass Cables (SBC) with Neutrik

50-amp Speakon™ plugs at each end.

7) A single Power Transformer for the Amplifier Modules

with two Neutrik™ 20-amp PowerCon™ outlets.

8) A pair of Power Umbilicals with a Neutrik 20-amp

Powercon plug at each end (one grey and one blue).

As an optional upgrade, comprising two Maximum Dynamic

Headroom Reservoirs and an additional Power Transformer is

available. This conveys additional macro- and micro-dynamic

Genesis 2 Servo-Controlled Bass Amplifier

absolute fidelity

capabilities to the servo-bass system. With this upgrade, two

additional Acoustic Suspension systems are supplied.

In the typical configuration, the Control Module, and two Servo-

feedback Amplifiers are placed in a stack between the midrange/

tweeter wings. The Power Supply is placed behind the stack. Using

the supplied Power Umbilicals, connect the Power Supply to the

two Amplifier Modules.

A word of caution – the Neutrik PowerCon connectors used

for linking the power supply to the amplifiers are designed for

passing current. They are not designed to make/break current.

Hence, be sure to connect the Power Umbilicals before you

connect the Power Supply to the wall outlet.

With the optional Maximum Dynamic Headroom Reservoir

upgrade, the Control module is placed in the middle, flanked by the

two Servo-feedback Amplifiers topped with the MDHR. The Servo-

feedback Amplifiers would ideally be set closer to the woofer

towers with shorter Servo-Bass Cables, and the Control module

can be placed between the midrange/tweeter wings.

Using the supplied CIC, link the Control Module to each of the

Servo-feedback Amplifiers. One amplifier module is for the RIGHT

woofer tower and the other will be for the LEFT. This can be

determined by the last letter of the serial number. It does not matter

which CIC is used for the right channel and which is used for left.

However, one is marked with a red ring and the other is marked

with a white ring for convenience.

Use the SBC to connect the woofer

towers to the woofer amplifier. Each

end of the cable has a pair of 50 amp

twist-lock Neutrik™ Speakon™

connectors, and is clearly marked,

AMPLIFIER or SPEAKER. It does not

matter which connector is used as

long as the correct amplifier module is

used for the left and right towers. It

does not matter which SBC is used for

the left or the right; however, one is

marked with

AMPLIFIER or SPEAKER in

red lettering, and the other in white

absolute fidelity

Servo-Bass Interconnects

lettering.

When you connect the woofer tower outputs pay close attention to

the way the connector works. It only goes in one way and you

cannot put it in wrong. However, you can fail to put it in all the way

or fail to lock it in place. Line up the alignment pins on the

connectors, push the plug in, and twist it clockwise until the lock

"clicks" in place to keep it there. By looking carefully, it will be

obvious as to how it works.

At the

AMPLIFIER end of the servo-bass cable, you will find a male 1/8”

jack. The female end is on the chassis of the servo-bass amplifier

labelled GND. These jacks are used for grounding an internal shield

within the servo-bass cable. For the time being, leave this shield

disconnected. The shield ground should be used only when

necessary.

Midrange/Tweeter Connections

Next, connect the mid/tweeter

panels to your power amplifier

using a pair of high quality

loudspeaker cables (not

supplied) to the 5-way binding

posts. We recommend using

good quality spade

connectors for this job.

There are two ways to get the

music signal from your hifi

system to the Servo-Controlled Bass Amplifier to drive the woofers.

The first, and preferred way is to drive it using the output of the

power amplifier that is driving the midrange/ tweeter panels using

the supplied pair of Servo-Bass Interconnects.

The Servo-Bass Interconnect will be supplied with a pair of banana

plugs at one end, and an XLR balanced male plug at the other end.

The banana plugs will plug straight into the binding posts of the G2

midrange/tweeter tower inputs when you are using speaker cables

with spade connectors. If your speaker cables use banana plugs,

you can order spade connectors with the SBI at no extra charge

when you order your loudspeakers.

The XLR connector contains a specially developed internal

absolute fidelity

balancing circuit that enables the power amplifier to drive the

balanced input of the servo amplifier. Because of the extremely

high impedance of the balancing circuit, the parallel connection

places absolutely no stress on the power amplifier. Do not use any

other interconnect cable for this purpose as the high level output

from your power amplifier will blow the input circuit of the Control

Module! This internal circuit also allows even fully balanced power

amplifiers

to be connected this way.

Plug the XLR end of the SBI into the Control Module and the

banana plug end into the binding posts of your midrange/tweeter

towers (preferred) or the output binding posts of your power amp.

Each end of the SBI has a grounding alligator clip on a flying green

lead. Leave this grounding clip disconnected for the time being. It

is not necessary in most instances.

The alternative method of connecting the servo-bass amplifier to

your system is to use a pair of balanced interconnects (not

supplied) from your preamplifier to the servo-bass amplifier. Your

preamplifier will need to have two sets of outputs, or you will need

to use a high-quality Y-cable (not supplied). If you use this method

of connection, your power amplifier will be driving the midrange/

tweeter towers and the servo-controlled bass amplifier will be

driven in parallel by your preamp.

As no power amplifier is “straight wire with gain”, we do not

recommend this way of driving your servo-bass amplifier. The

reason is that coherence and good integration between the

midrange and bass is much harder to achieve.

Servo-Bass Amplifier Remote

Your Genesis 2.2 servo-bass amplifier is supplied with a Logitech

Harmony™ remote control. This is a universal remote control that

can also be programmed to control the rest of your music system.

While we do not provide customer support for the programmable

functions (please check www.harmonyremote.com

for that) we

supply it pre-programmed with the correct codes to control the

Bass Control Adjustments

Your servo-bass amplifier should be the last thing you turn on in

your system, and the first thing you turn off. As a general rule, turn

your system on starting at the source to the amplifiers, and turn it

off starting at the amplifiers back to the source.

If the remote is not already set-up to control the Servo-

Bass Amplifier, press the [Devices] button on top, and

select Amplifier on the screen by pressing the button next

to it. Plug the woofer amplifier into a power outlet

, and

using the remote control, turn it on by pressing the OK

button. The display on the Control Module shows

onon

on .

When you make any adjustments, the display flashes

to identify the function that is being adjusted.

The bass volume or gain is controlled with the Ch. +

and – buttons. (The Vol + and – buttons are used for

your main volume control on your preamplifier.) When

you first press one of the volume control buttons, the

currently-set volume will flash. The next press will

move the volume up or down. Pressing and holding

the Ch. + or – buttons will change the volume up or

down rapidly.

The bass volume/gain has a range of 0 to 100. A volume

setting of around 40 is nominal

for normal sized rooms. That is a

If you have managed to let us know ahead of time what the rest of your system is, it

might even be possible for us to pre-program the remote for you.

Do NOT use any power conditioners with the Genesis Servo-Controlled Bass Amplifier.

We have found that every power conditioner that we have tried will restrict the dynamics of

the system – except the Titan by IsoTek Systems.

This assumes that the standard SBI is used to interconnect the Control module to the

midrange/tweeter towers.

absolute fidelity

good place to start when making adjustments. In general, a lower

bass volume setting is needed in smaller rooms.

Next, adjust the phase with the buttons marked “” or “” on the

remote

control. When you first press the phase up or down button,

the display will flash

PhPh

Ph and then the current phase setting will be

shown. The next press of the button will move the phase up or

down. Set the phase to zero as an initial setting.

If you are not driving the servo-bass amplifier as recommended

using the output of the power amplifier and the Servo-Bass

Interconnect supplied, the phase will depend on the phase shift and

group delay of your power amplifier. A typical value can be

anywhere from 45 to 135 degrees. A phase inverting power

amplifier will require that you invert the input phase of the Servo-

Controlled amplifier.

Two crossover controls are provided on the Control Module that

helps you tune the system into your room. The high-pass filter

determines how low the woofers will play, and the low-pass filter

determines how high the woofers play to. The frequency that you

set these filters to will be the “knee” frequency after which the

woofers will attenuate by 6dB per octave, and is not the –3dB point.

The high-pass filter and low-pass filter is set using the

up/down/left/right navigation ring around the OK button.

Up/down adjusts the high-pass filter up and down

respectively, and right/left adjusts the low-pass up and

down respectively.

Initially, set the high-pass (

HIHI

HI) filter to 26Hz until the

woofers and amplifiers break in (about 300 hours of play).

After which it can be set to 20Hz. Next, adjust the low pass

(

LOLO

LO) filter to 98Hz using the button marked "low pass" (on the

remote control).

In addition to the current setting, the Control Module can memorize

up to two sets of settings. To recall the settings in Memory 1, press

the [1] key momentarily. To recall the settings in Memory 2, press the

[2] key momentarily.

To store the current settings in Memory 1, press and hold the [1] key

for approximately 5 seconds or until the display flashes. To store the

current settings in Memory 2, press and hold the [2] key for 5

seconds or until the display flashes.

Midrange/Tweeter

Controls

You will notice two controls on

the back of the midrange/

tweeter panel. The left hand

knob is a trim control for the

rear tweeters. Turning this

control clockwise will increase

the level of the rear tweeters.

If there is not enough space

behind your loudspeaker, the

rear tweeter control can be

turned down. In large rooms,

the tweeter control can be turned up. Use this control if you need a

bit more treble or to increase the apparent space of the

soundstage. Start with this control at the twelve o'clock position.

The control on the right side is a three-position switch used to

adjust the midrange. Start at position two. Position one will sound

fuller in the lower midrange while position three will sound leaner

and have more upper midrange.

The less obvious effect (more obvious to some people!!) of the

midrange control is to make the soundstage sound more forward,

and change the perceived height and position of the performance.

Relative to position two, you can raise the soundstage by moving to

position three (it’s like moving your seat forwards in the concert

hall!!)

Position two gives you a soundstage perspective of about the

middle of the concert hall. Position three is more like the orchestra

seats, and position one may be more like the circle seats.

While it is relatively easy to put the Genesis 2 loudspeaker system

into your room and system and get a reasonable sound, it is not as

easy to perfectly integrate the loudspeakers into your room, and

get great music out of it. The time you will take to do this properly

will be well worth it for the long-term enjoyment you will derive. This

fine-tuning is covered later in this manual.

absolute fidelity

Servo-Controlled Bass Amplifier Protection

The servo-bass amplifier has numerous protection circuits built in to

protect both the amplifier and the woofers. If you over-drive the

amplifier, it will self-protect and you will hear clicking or thumping

sounds. This is caused by the amplifier limiting current to the

woofers (much like the over-rev fuel-cut off in sports car engines).

If that happens, turn down the volume of your system to protect

your hearing and your speakers. The amplifier is designed to be

current-limited to 20amps – this is more than enough to supply over

1600W transients to the woofers. However, the servo-system in the

G2 is not compression or dynamic limited. Hence, it is possible to

play the system too loud, and damage the woofers (and also

possibly blow your ribbons).

Due to the efficiency of the amplification modules, they deliver

and draw current extremely quickly. Even though in a well-wired

home it is unlikely, you may find that a very loud bass drum thwack

will cause your lights to dim, or the circuit breakers to trip if you do

not supply enough power to your system.

A possible solution will be to install an additional 20amp circuit in

your listening room, and purchase an additional power supply to

separate the power needs of the left and right woofer towers. Also,

the Maximum Dynamic Headroom Reservoir (developed for the

Genesis Reference Amplifier) is available as an optional upgrade.

A Word about Finish

The G2 is entirely covered in high-gloss acrylic. Acrylic was picked

for its sonic properties as well as its beauty. However, acrylic is a

soft material that can scratch easily.

Every G2 system is delivered with a 3-stage acrylic polish system

by Novus. Do not use any other cleaners or polish on your G2

loudspeakers. In particular, DO NOT use paper towels to wipe the

surface of your loudspeakers. Paper fibres are extremely abrasive

and can introduce fine scratches on the surface. If dusting is

necessary, we recommend a soft feather duster.

absolute fidelity

Tuning the system

Music is the best way to begin to fine-tune your setup. We suggest

that video sources be used only after you have setup the system to

properly reproduce music. While we deliver the G2 system only

after at least 24 hours of running-in, fine-tune your system only

after at least 200 hours of play. As the loudspeaker system breaks

in, it will sound better and better.

Begin with the bass level

Start with a single vocal with simple instrumental accompaniment

because the sound of the human voice is more easily recognizable

than many instruments and is the least complex sound to deal

with.

Leave the low pass filter alone for the moment, as it should remain

set at 98 Hz, This control will be addressed later. Turn the volume

control of the woofer amplifier up or down until the voice sounds

correct. Whatever controls you use, turn them up and down only a

little at a time. It is easy to turn it up or down too much.

Concentrate on the mid bass regions (as opposed to the very low

bass in your recording) to achieve a natural blend. The voice and

the music accompaniment should sound as if it were cut from one

cloth, not separate.

If the voice sounds “thin” or does not have enough “chest” to its

sound, turn the woofers amplifier’s volume up till it does. If you find

that turning the volume up creates too much low bass, then it is

time to decrease the low pass filter control.

The low-pass control will raise or lower the frequency cutoff point of

the woofer. Turning the low pass filter up to a higher number will

extend the upper bass regions without affecting the low bass level.

Some rooms may require that you set the low-pass filter to 100Hz.

Do not be afraid to increase this control to give the sound more

body.

Next, set the woofers using more than just a voice. Select some

music that you know to have good deep bass. Using the volume

control on the servo amplifier’s remote control, set the woofers for a

natural and powerful bass sound. Use a symphonic piece of music

if you can, or use a natural bass instrument like a stand-up bass for

absolute fidelity

your guide. Try to make it sound real. You may have to return to

the vocal to make sure you have not gone too far in one direction.

If, at this point, it does not have enough mid bass, turn the low pass

number to a higher position or, alternately, position the midrange/

tweeter wings closer together in order to achieve better lower

midrange coupling between the main speakers. If it sounds too “fat”

turn the low pass control down or adjust the volume. At this point it

is suggested to use the low pass filter control until you get to the

refinement stage.

Imaging and Soundstage

While imaging and soundstage are a controversial subject (how do

you ever know that the soundstage is recorded correctly in the first

place), it is vitally important to our enjoyment of a recorded musical

event. The G2 is able to deliver a realistic soundstage only if the

recording contains such realism.

If your vocal selection is a well-recorded audiophile CD or LP, the

performer should appear to come from behind the loudspeakers

and be at the appropriate height for a standing person. If it is not,

there are several remedies that will address this.

Assuming that the vocal recording is accurate, if the vocalist

appears to be larger than life, you should first check the system

volume. Is it a volume that would be appropriate for someone

actually singing in your room? If there is too much volume the

artist will appear too big and the opposite is true for too little

volume. If the volume is set correctly and the image is still too big,

toe the woofer towers in a very slight amount or place them

closer together and re-listen. Repeat this process till you have it

right.

If the voice is too low in height, turn the midrange control to the

next highest position and the image of the voice will move upward.

There are many solo vocal recordings where the singer is recorded

using a microphone hung above head height. In this case, it is

correct for the system to portray a singer that seem to be singing

from a pit in between your loudspeakers.

If you have the speakers only 20% away from the front wall, and

you are not getting enough front to back depth (the singer not

appearing behind the speaker enough) pull the midrange tweeter

absolute fidelity

panels away from the front wall a little bit at a time. If you do not

have them pulled far enough away, you may not have enough

front to back depth. If you get the speakers much beyond 1/3 of

the way into the room, it is unlikely that pulling them further away

is reasonable.

Too much absorption on the wall behind the speakers will also

result in less depth in the soundstage. The G2 requires a

relatively “live” front wall.

Find the best compromise for your room, your tastes and your

space requirements. If the speakers are too far apart you will lose

the side image and the image density in the middle of the

soundstage will be too diffuse. If the speakers are too close

together you will have too small a center stage, and you may find

that the edges of the soundstage collapse inwards.

We recommend you begin with six to seven feet apart as

measured from tweeter to tweeter. If you are not getting proper

focus on the voice, you may angle the midrange panels from 1 to 3

degrees inwards towards your seating position until you have a

properly defined center image.

When properly set up very little sound should appear to come

directly from the speaker, instead, the sound stage should extend

far beyond the left and right edge of the loudspeakers and they

should have tremendous front to back depth. When the recording is

close miked (when the instrument or performer is very close to the

recording microphone) the music may appear to come directly

from the loudspeaker. This is normal. Typically, however, the

sound should appear to be detached from the loudspeakers.

A simple rule of thumb to follow is that focus will be achieved by

placing the speakers closer together or farther apart, and front to

back depth can be adjusted by the distance from the front wall and

treatment (or lack of) of the front wall. Further, as the system

“breaks in”, the depth and width of the soundstage will increase,

and so will the “smoothness” of the sound.

Phase Control

We suggested in the beginning of this manual to set the phase to

zero degrees when the Servo-Bass Interconnects are used. If a

balanced pre-amp level input is used, the phase angle may be

absolute fidelity

anywhere from 45 deg to 135 deg (or require that the input to the

Control Module be phase inverted if the power amplifier used is

phase inverting).

Now that you have roughed the system in, you may want to

experiment with different phase angles. Using the remote control

you can adjust the woofer's phase angle up and down in five-

degree increments.

The changes are subtle and they usually affect the imaging and

soundstage. Listen carefully to the positioning (in acoustic space)

of the orchestral players as you change the phase control. You

may notice small shifts in their apparent relationship to the other

members of the orchestra. Do not expect them to actually move.

Expect minute changes in the soundstage, the apparent width of

the stage, your ability to distinguish individual players etc. If you

reach a phase shift of ninety degrees you have probably gone too

far. Using the recommended connection, the phase shift needed is

usually 15 degrees or below.

The other change to listen for is rhythm and timing. Adjusting the

phase will subtly change the relationship between the bass and the

midrange. When you get the phase perfectly correct, you will find that

the timing between the vocalist and the double bass “snaps” in place,
